Rubina was being shown around Neige and Rouge's room.

"Look, this is it!"

"He...... hee......"

<, the couple entered an underground passageway that led to a grotto in the rock wall. The third floor is their room.

Rubina, as expected, is a little bit nervous.

The walls, floor, and ceiling of their room are painted white, and the only furniture in the room is a king-size bed and a small sideboard on which they must be sleeping.

The only furniture was a king-size bed and a small sideboard that might have been used for sleeping two people.

"...... Is there any other furniture?　Maybe a chest of drawers or a closet. ......"

Rubina asked, and the two of them both bit into her words.

We don't know much about that kind of thing.

"Rubina, can you tell us about all these things?"

And Rubina was glad to be asked to help,

"Yes, sure!

She accepted the offer.

Meanwhile, as for the adults,

"This is the dome ......"

< side. There are three huge domes that used to be over 100 meters in diameter.

The domes are broken and most of the cubic zirconia has been reused.

The houses that may have once stood inside the domes have been reduced to rubble, unable to withstand the passage of more than 10,000 years.

"There must have been many of these things in the Nordic Federation."

That's where cubic zirconia is found.

Amanda suggested that we invite Rubina to join us, but 700672, seeing Rouge and Neige looking so happy, said, "I want you to leave it as it is. Amanda said, "Leave it as it is.

"Yes. < liked it this way."

By building a giant transparent dome and maintaining a comfortable environment inside with light shielding and air conditioning, they could live anywhere from the tropics to the frigid zones, 70067 No. 2 explained.

"That's what we made much smaller to imitate."

700672 pointed to a small dome made by Jin.

"It looks nice. It looks warm when it's cold."

Marikka, who is from the relatively cold <>, looked at the dome a little enviously.

"Well, let me show you inside."

Marikka's words were followed by the 700672 group ......Marikka, Marikka's words, and the 700672 group is led into the dome by Marikka, Trihart and Suzanne, Amanda, and others.

Meanwhile, Jin and Reiko were at the grotto because they were worried about Rubina and the others.

They are watching them from a distance.

Like a father watching his daughter's , Jin watches them from the shadows.

"(They've become very good friends. ...... I guess I can rest easy now. ......)"

"(Yes, father.)"

The three of them are now going to the observation deck. They got into the elevator that had just been completed. Jin asks Reiko to help him, since he can't follow them.

"Reiko, keep an eye on them with the peepers, just in case."

"Yes, Father."

* * *

"Wow, nice view!　...... Oh, there are the grandmothers."

Rubina was thrilled to be in the observation deck with a 50-meter difference in elevation.

Neige and Rouge are used to it by now, so they are not so excited.

"I love ...... this place."

Rubina looks deeply envious of Neige and Rouge,

"You can come visit us anytime you want."

"Yes, yes. We're friends, aren't we?

They said to her.

When Jin hears this from Reiko, he is relieved to hear that everything will be all right.

Then he decided to stop stalking her and quietly went outside with Reiko.

Just then, 700672 arrived with Marikka, Mr. and Mrs. Trihart Susanne, and Amanda to show them the grotto. Amanda.

"Oh, Mister Jin was here?"

"Yes, I was looking out for Rubina, Neige and Rouge.

I'm sorry about that. So how did it go?

They're getting along great. They're getting along great.

"That's superimposed."

700672 laughed happily.

And Amanda,

"She's always been a shy girl, you know.

Amanda smiled, "She has always been a shy girl.

Amanda smiled, "She has always been a shy girl.

"This place has a nice view, doesn't it?

In the end, we all went to the observation room.

Rubina, Neige, and Rouge, the first guests, greeted everyone with smiles.

"Rubina, I see you two have become friends.

"Oh, grandma. Oh, grandma!　Rouge and Neige are friends now!

"Yes. Rouge, Neige, be good friends with my grandchildren.

Amanda said to Rouge and Neige.

"It's nice to meet you, too!

"I'm looking forward to working with you."

Both of them replied smilingly.

When it was time for lunch, Jin led the group to the .

The <700672 was not stocked with food for ordinary people to eat. Nor was there a kitchen.

(We need to stock food for visitors and set up a kitchen. ...... And we need a samurai golem that can cook.)

) Jin thought to himself.

"So this is Jin-sama's house. It's a very calm house, isn't it?

"Oh, the house itself is just like Hourai Island!

"You've already built this much?

"Is this the real architecture?

"It looks like a nice house to live in, dear."

Amanda, Rubina, Marikka, Trihardt and Susanne said.

"Come in."

Jin leads them to the living room. Everyone knew to take off their shoes.

"Welcome.

We have been waiting for you.

Having been notified, the Japanese-style samurai automata and were waiting for them, ready to serve lunch.
